Is this panel half-cut
A1 SolarStore
It sure is — 144 cells means it’s a half-cut 72-cell design for better shade tolerance.

FAQ

How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South

About product

Among the newest offerings of Regitec, RMH72-550S1 is part of the RMH72-525~550S1 series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

The use of half-cut cell technology is an additional perk. The solar cells of RMH72-550S1 are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. The efficiency of this model reaches 21.3% — well above the market’s average. Regitec paid as much attention to durability as they did to performance. RMH72-550S1 is guaranteed to retain at least 80.68% of output after 30 years. Product warranty for this panel lasts 25 years.

  • 550 W power output
  • 144 half-cut PERC cells
  • 21.3% efficiency
  • 1500 V DC maximum system voltage
  • MC4-compatible connectors
  • 25-year product warranty and 30-year performance warranty

Increased efficiency of up to 21.3%

RMH72-550S1 ensures maximum power production. 21.3 percent module efficiency is achieved using PERC technology and a powerful antireflective coating. This is much greater than the norm, resulting in significant additional savings throughout the years of operation.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. RMH72-550S1 loses just -0.35% of efficiency for every 1.8°F above 77°F.

High quality standards

Regitec stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Regitec guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 3% the first year, and then only by a maximum of 0.56% yearly after that. After the 30 years are over, your modules will still show at least 80.68% of nominal capacity. A substantial 25-year product warranty is also included with this 550 W Regitec solar panel.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum alloy and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.

Real-world feedback demonstrates Regitec's reliability:

"First time buying Regitec and wow these things deliver."

"Got the Regitec 430s for my new ground mount system. They perform better than I expected."

Field testing confirms strong performance metrics. A panel tester on one in good sun got pretty much the nameplate rating if not a bit more on a clear day in Kansas. They seem pretty nice. It may take years to know if they were truly any good, but first indications are solid.
